About this spectrum2 notes
Source & details
Source category: estimated
Estimated response: not a primary measurement (e.g. diffraction-grating closed-form recovery, model prediction). Independent of profile_type and quality/confidence grades.
Type: estimated
Estimated response, not a direct measurement; quality and confidence are assessed separately.
Quality: unassessed
Quality has not been assessed; no grade is inferred. Raster graph digitization; source measurement uncertainty is not documented.
Confidence: unassessed
Confidence has not been assessed; no confidence level is inferred. Exact chip and mode documented; complete camera equivalence is not established.

Methodology

As-is
Samples rendered verbatim: no smoothing, no interpolation, no zero-padding, no gap bridging in the browser. Documented null sparse cells render as visible gaps.
Uncertainty
Extraction tolerance is documented in the downloadable JSON; it does not quantify source measurement uncertainty.

Known limitations
  • A single monochrome trace changes display color with wavelength; those colors are not separate RGB channels.
  • The manual has inconsistent IMX455AQK-K/ALK-K part suffixes; the curve is associated with the explicitly monochrome camera and generic mono IMX455 family only, not a particular die suffix.
  • Camera AR window contribution is not separated. No data beyond 700 nm are supplied by this graph.
  • Digitized manufacturer reference for ZEUS 455M Pro. Other cameras using this sensor can have different filters and windows.

Player One ZEUS 455M Pro camera manual

Image area and resolution are documented for this reference camera; other cameras may use a different crop or binning mode.

Player One's manual prints IMX455AQK-K while other Sony documents distinguish the mono ALK-C and color ALK-K variants; the catalog identity stays at family level.

Sensor-level response data is available. Camera filters and windows can change the complete camera response.

Color and monochrome versions are listed separately; their curves are not interchangeable.

Source evidence
  • Altair Astro AA61CFX: Altair's official model/sensor table groups AA61CFX / MFX under IMX455; CFX is the color identifier by model naming. MFX is recorded separately as mono. Manufacturer source
  • Altair Astro AA61MFX: Altair official grouped sensor row lists AA61MFX under IMX455; MFX is the monochrome model designation. Manufacturer source
  • PlayerOne Astronomy ZEUS 455M Pro: Official 2026 cooled camera specification table gives ZEUS 455M Pro, IMX455 mono, 9576×6388 and 3.76 μm. Manufacturer source
  • QHYCCD QHY600M-PH: QHY600 series table identifies the M-PH monochrome variant and Sony IMX455. Manufacturer source
  • ToupTek Astro SkyEye62AC Plus: Official paired model page identifies SkyEye62AC Plus as color IMX455; its matched AM mono body is listed separately. Manufacturer source
  • ToupTek Astro SkyEye62AM Plus: Official ToupTek description explicitly calls the camera IMX455M, full-frame mono. Manufacturer source
  • ZWO ASI6200MM Pro: Official ZWO manual index lists ASI6200MC/MM Pro; ZWO's ASI6200 family specification identifies IMX455. Manufacturer source
